Hoodies have had their day. The tech world’s uniform has shifted — and for the moment venture capitalists, startup founders and entrepreneurs have settled on gray wool Allbirds sneakers. According to the brand’s origin myth, the shoes were created by a former New Zealand soccer star who was turned off by the corporate world’s uncomfortable footwear. It’s no surprise Allbirds is taking over with its knit-wool, machine-washable sneaker-like kicks. I also appreciate that the brand is co-helmed by forward-thinking, clean-technology entrepreneur Joey Zwillinger.
